Patent EP-0291225-A3 (EP)
IPC: B01D53/50
Filed: 1988-05-05
Abstract: The present invention relates to a process 
for causing gaseous trace element particles 
to pass from a flowing hot gas into a dust 
by means of water. According to the inven­
tion, a mixture of the hot gas and water 
drops is caused to flow substantially up­
wards at such a velocity that the water 
drops remain in the gas flow and for a 
period long enough for most of the mass of 
the water drops to evaporate in order to 
cool the gas and to increase its relative 
humidity. After the gases have reached 
their wet temperature they are brought into 
a turbulent state in order to cause the 
dust particles and the water drops which 
have decreased through evaporation to im­
pinge against each other in order to pro­
duce in the aqueous film which covers the 
dust particles an exothermal ion reaction 
between the gaseous water-soluble trace 
element particles and the dust particles. 
Thereafter the mixture is caused to flow 
further in order to evaporate the remaining 
water by means of the heat of reaction so 
that a dry end product is obtained.

focussed interrogating beam (JRB).
Patent EP-0373781-A3 (EP)
Title: Spring biased drive socket insert for centrifuge rotors
IPC: F16D1/091
Filed: 1989-11-24
Abstract: A composite rotor body (P2) has a drive hole insert (4) 
attached. The drive hole insert (4) seats along a conical 
surface (67). A disk spring (72) bears 
against a washer (74), which in turn 
bears against the top surface of the composite material rotor 
body (P2). The preloaded disk spring (72) 
compresses the conic surface (67) 
of the rotor body (P2) against the mating surface (69) of the drive hole 
insert (4). The preload within the disk spring (72) is activate by 
torquing centering nut (70) until the disk spring (72) is essentially 
flat. The centering nut (70) captures and centers both the disk 
spring (72) and washer (74) within a counterbored recess on its bottom 
face. The contact surface is treated with a form of dry 
lubricant or release agent, typically particulate Teflon, such 
that axial translation is facilitated. The disk spring (72) is 
sized such that the drive hole insert (4) translates axially 
without rotation along the surface and, effectively, maintains 
constant in-plane orientation with respect to the rotor body (P2). 
This occurs as the diameter of the through-the-thickness hole 
in the rotor body expands and contracts due to operational 
loads.

Patent EP-0393436-A3 (EP)
IPC: G11C11/41
Filed: 1990-04-06
Abstract: Die Erfindung betrifft einen statischen Speicher mit mehreren 
Hierarchieebenen (H0...H3) und eingefügten Pipelineregistern. 
Hierfür werden günstige Realisierungsmöglichkeiten angegeben, 
da der Flächenaufwand für die Ansteuer- und Ausleseschaltungen 
in der ersten Hierarchieebene (H1) besonders kritisch sind. 
Vorteilhaft werden hierbei Speicherzellen eingesetzt, die getrennte 
Schreib- und Lesewortleitungen sowie getrennte 
Schreib- und Lesedatenleitungen aufweisen, die weiterhin ein 
starkes Zellsignal liefern, so daß ein geringer Aufwand der 
Leseschaltung nötig ist. Für den betreffenden Speicher wird 
ein neues Taktschema mit einer Anordnung von Pipelineregistern 
vorgeschlagen, mit dem durch Abschalten der Takte in den unteren 
Hierarchieebenen die Leistungsaufnahme reduziert und die 
Flächenersparnis erhöht wird.

Title: Cover for a luggage compartment for automobiles
IPC: B62D31/00
Filed: 1990-06-13
Abstract: A cover for a luggage compartment for motor vehicles, in particular for estate cars, has a cover tarpaulin which can be guided longitudinally by means of support rods in guide rails and folded. Each support rail is held in the two guide rails with C-profiles in a manner which is essentially immune to tensile forces and pressure forces in relation to the longitudinal central axis of the support rod 19 by means of its end-side guide body engaging there. In order to avoid jamming due to tilting in an oblique position of the support rods, provision is made for the end face, which points towards the inner surface of the guide rail-side profile floor, and/or the inner end face, which points towards the flanges, of each guide body to be provided with at least one convexly curved contact area for the inner face of the profile floor and for the inner face of the flanges, respectively. <IMAGE>

Title: Permeable nozzle method and apparatus for closed feeding of molten metal into twin-belt continuous casting machines
IPC: B22D11/06
Filed: 1990-10-22
Abstract: The closed-channeled, multi-passaged nozzles have gas-permeable refractory walls, allowing the escape of gases that may be dissolved in the molten metal and become expelled or liberated from it while the molten metal is flowing through the passageways in the nozzle. Gaseous voids in the continuously cast product are thereby avoided, notably in aluminum casting as shown by experimental results to date. The nozzles are made from gas-permeable refractory material having interconnected porosity -- that is, interconnected void interstices -- extending through the nozzle walls. The interconnected void interstices are of sufficient size for allowing the passage of hydrogen gas through the walls, while being sufficiently small for preventing the leakage of molten metal. The gas-permeable refractory material is relatively non-wettable by the molten metal. For example, the nozzles are made of fibrous sintered refractory material -- for instance, fibers of alumina or silica intertwined and cohered within a major volume-percentage of interstitial voids, which provide the interconnected porosity. Such fibrous material displays high resistance to thermal shock. It is relatively compliant to nozzle clamps, with consequent resistance to breakage, while the coefficients of thermal conductivity and thermal expansion of such fibrous refractory material are advantageously low.

Title: Method and apparatus for computer program encapsulation
IPC: G06F9/06
Filed: 1990-05-24
Abstract: A method and apparatus for encapsulating an 
application tool (42) into a computer-aided software 
development system that includes a number of 
standard software development tools 
(10,12,14,16,18). The application tool is 
integrated into the software development system 
without modification of its code. An interface 
description file (48) that defines desired 
operations in responding to predefined events 
received from the development tools and from a user 
interface is compiled (72) to generate a symbol 
table (52) and a statement table (54). The symbol 
table and the statement table are evaluated (73) to 
generate objects (60) which define operations that 
are performed when responding to the predefined 
events. An event handler (62) responds to the 
predefined events received from the development 
tools and from the user interface by evaluating 
objects (60) corresponding to the predefined events 
and executing the operations defined therein. 
Notifications received from the development tools 
can be utilized to trigger predefined operations by 
the application tool (42). A subprocess controller 
(68) permits the application tool (42) to be run 
locally or on a remote host computer.

Title: Operational amplifier having selectable inputs
IPC: H03F3/68
Filed: 1990-07-05
Abstract: There is disclosed an operational amplifier (10) which is arranged for sensing the voltages provided by a plurality of input voltage sources and which diminishes the level of noise at the operational amplifier output resulting from the selection of the input voltage sources. The operational amplifier (10) includes a first amplification stage (12) having first and second voltage sensing inputs (38, 40), a common input (36), and an output (28, 34), and a second amplification stage (16) having an input (42) and an output (52). Switch means (14) are disposed between the first stage output (28, 34) and the second stage input (42) for selectively coupling the amplified signal at the first stage output resulting from an input signal at the first input (40) to the second stage input (42) or the amplified signal at the first stage output resulting from an input signal at the second input (38) to the second stage input (42). Because the switch means (14) is disposed between the first (12) and second (16) amplification stages, the noise coupled into the operational amplifier (10) is not amplified by the first amplification stage and hence, the noise at the output of the operational amplifier (10) is deceased by a factor equal to the gain of the first amplification stage (12).
